Which option correctly identifies the two passive fire protection measures?

• A. Fire rated walls and special coatings on structural components
• B. Automatic sprinkler systems and fire alarms
• C. Fire alarms and smoke detectors
• D. Exit signs and emergency lighting

Answer: (A)

Passive fire protection relies on features built into the structure that resist fire and slow its spread without needing any action or energy input. Fire-rated walls and coatings on structural components fit this idea because they maintain compartmental integrity and insulate against heat, helping to contain a fire and buy time for occupants and responders.

The other options involve active measures or life-safety features that don’t hinder fire growth. Automatic sprinkler systems and fire alarms require water, energy, or signaling to operate. Fire alarms and smoke detectors are detection systems rather than containment. Exit signs and emergency lighting aid egress but don’t stop or slow the fire itself.
